for anyone trying to use this to create the index through dev tools; remove the type parameter as it has been removed by elasticsearch
This should work

the way you explain is soo cool!

[@HemantP-s8x]

HI Vipul,
Can we get exam practice question set, how questions may asked in Elastic Certified Engineer and also small session on ILM policy.

[@HemantP-s8x]

Hi Vipul,
Can you please share practice question set as per Elastic Certified Engineer exam.

[@brundhavanip1818]

Can we able to substract two fields values. Using metric aggregation and buckets aggregation in dashboard panel? The subtraction values should display in separate column in panel.

[@ajithshylin3159]

Hi, i have one doubt that is how to include text fields in aggregate query in elasticsearch version 1

[@emailshe]

Eiter have a sub type as keyword. in the mapping. Another option is to create a runtime_mapping in query time (takes more memory)
